## Architecture Highlights

### ✅ Modular Design
- Each category isolated in its own file
- Clear separation of concerns
- Easy to maintain and extend

### ✅ Type Safety
- Full TypeScript support
- Zod schema validation on all inputs
- Branded types for IDs (prevent mixing invoice/contact IDs)

### ✅ Xero API Compliance
- PUT for updates (not PATCH)
- GUID-based identifiers
- Batch operation support
- If-Modified-Since polling
- Page-based pagination (max 100)
- Proper header handling via client

### ✅ MCP Standard Compliance
- Tool naming: `xero_verb_noun`
- JSON schema for all inputs
- Comprehensive descriptions
- Required vs optional parameters clearly marked

## Verification Results

### TypeScript Compilation
```bash
$ npx tsc --noEmit
# ✅ No errors
```

### Module Loading
```bash
$ node -e "import('./dist/tools/index.js')..."
# ✅ Tools index exports: [ 'getAllTools', 'getToolCount', 'handleToolCall' ]
# ✅ Module loaded successfully
```

### Tool Count
```bash
$ grep -r "name: 'xero_" src/tools/ | wc -l
# 84 tools (target: 60-80)
```

## Next Steps (Optional Enhancements)

1. **Testing**
   - Add unit tests for each tool category
   - Integration tests with Xero sandbox
   - Mock client for CI/CD

2. **Payroll API**
   - Implement full Xero Payroll API
   - Separate auth flow (Payroll requires different scopes)
   - Region-specific payroll (AU, UK, US, NZ)

3. **Advanced Features**
   - Batch operations (process multiple records at once)
   - Webhook support for real-time updates
   - Advanced filtering DSL
   - Custom field support

4. **Documentation**
   - Add JSDoc comments to all functions
   - Create usage examples
   - API reference documentation
   - Video tutorials

5. **Performance**
   - Implement caching layer
   - Request deduplication
   - Parallel batch processing

## Foundation Already Exists

**Not modified** (as per task requirements):

✅ `src/types/index.ts` - Complete type definitions  
✅ `src/clients/xero.ts` - Full API client with rate limiting  
✅ `src/main.ts` - Entry point  
✅ `package.json` - Dependencies configured
